LIQUID WAX FOR THREADS.

No Drawing. Application filed January To all whom it may concern:

Be it known that I, Jon FRY, a citizen of the United States, and aresident of Canton, in the county of Madison and State of Misssissippi,have invented certain new and useful Improvements in Liquid ax forThreads, of which the following is a specification.

This invention relates to a wax particularly adapted for use in waxingthreads and has for its object the provision of a fluid in which noingredients are used which will soil fabrics or leather when securedtogether by threads treated with the liquid, but nevertheless will beeffective for preserving and water-proofing the threads thereby pre'venting the usual breakage of the threads and a consequent separation ofthe sole and welt of a shoe.

A further object of the invention is the provision of a liquid wax fortreating threads used in the manufacture of leather goods and forpreserving the threads against ready breakage, the wax retaining itsliquid state regardless of the temperature, and being of suchconsistency that the fibers of the thread will be thoroughly impregnatedwithout leaving a surface coating which will mar the fabric when sewed.

This invention. will be best understood from a consideration of thefollowing detailed description; nevertheless it is to be understood thatthe invention is not confined to the disclosure, being susceptible ofsuch changes and modifications which shall define no material departurefromthe salient features of the invention as expressed in the appendedclaim.

In carrying out my invention I have endeavored to produce a wax whichwill be free of rosin because the rosin tends to clog or corrode thevarious parts of the machine during the sewing operation, therefore thefollowing ingredients and in the quantities named are employed-- Parts.Shoemakers prepared machinery wax 70 Boiled linseed oil 2O Banana oil 5Oil of Sassafras 5 27, 1925. Serial No. 5,144.

These ingredients are placed in a contamer and raised to the boilingpoint and maintained at such temperature until an in tmlate mixture ishad and then the liquid is allowed to cool. It must be borne in mindthat if the liquid thus produced is not of the proper density forcertain purposes a greater quantity of shoemakers wax may be added andthe liquid boiled again. here the density of the liquid is too greatafter cooling, boiled linseed oil may be added. The wax thus preparedwill be maintained in a liquid state and used in the usual way with shoemachinery. Since the wax has been dissolved or thoroughly incorporatedin the oils the wax will remain in solution and the product will presenta liquid state.

The shoemakcrs prepared machinery wax may be ordinarily described asbeing formed by melting together the best Swedish pitch and tallow in avessel over a fire, the quantity of tallow being determined byexperiment. The desired pitch is of a brown color when fractured.

The banana oil is introduced to prevent adhesion of the mixture to themachine. The oil of sassafras prevents any lumping of the wax, producinga smooth homogeneous mixture which thoroughly penetrates and saturatesthe thread, increasing flexibility and durability and prevents allstaining and spotting of work so necessary where leather and finefabrics are sewed together. This compound, as stated before, increasesthe durability of the thread so that there is no ripping so long asthere is any body to the leather at all.

lVhat I claim is:

A liquid wax comprising the following: shoemakers prepared machinerywax, 70 parts; boiled linseed oil, 20 parts; banana oil 5 parts and oilof sassafras 5 parts.
